Wright Maps are\ncommonly used to present the results of dichotomous or\npolytomous item response models. The 'WrightMap' package\nprovides functions to create these plots from item parameters\nand person estimates stored as R objects. Although the package\ncan be used in conjunction with any software used to estimate\nthe IRT model (e.g. 'TAM', 'mirt', 'eRm' or 'IRToys' in 'R', or\n'Stata', 'Mplus', etc.), 'WrightMap' features special\nintegration with 'ConQuest' to facilitate reading and plotting\nits output directly.The 'wrightMap' function creates Wright\nMaps based on person estimates and item parameters produced by\nan item response analysis. The 'CQmodel' function reads output\nfiles created using 'ConQuest' software and creates a set of\ndata frames for easy data manipulation, bundled in a 'CQmodel'\nobject. The 'wrightMap' function can take a 'CQmodel' object as\ninput or it can be used to create Wright Maps directly from\ndata frames of person and item parameters.", "License": "BSD_2_clause + file
